Blockchains and Smart Contracts for the Internet of Things

TLDR
The conclusion is that the blockchain-IoT combination is powerful and can cause significant transformations across several industries, paving the way for new business models and novel, distributed applications.
Abstract
Motivated by the recent explosion of interest around blockchains, we examine whether they make a good fit for the Internet of Things (IoT) sector. Blockchains allow us to have a distributed peer-to-peer network where non-trusting members can interact with each other without a trusted intermediary, in a verifiable manner. We review how this mechanism works and also look into smart contracts—scripts that reside on the blockchain that allow for the automation of multi-step processes. We then move into the IoT domain, and describe how a blockchain-IoT combination: 1) facilitates the sharing of services and resources leading to the creation of a marketplace of services between devices and 2) allows us to automate in a cryptographically verifiable manner several existing, time-consuming workflows. We also point out certain issues that should be considered before the deployment of a blockchain network in an IoT setting: from transactional privacy to the expected value of the digitized assets traded on the network. Wherever applicable, we identify solutions and workarounds. Our conclusion is that the blockchain-IoT combination is powerful and can cause significant transformations across several industries, paving the way for new business models and novel, distributed applications.

Blockchain implemented method and system

TL;DR: In this article, the authors proposed a method for performing an exchange via a blockchain, comprising the step of submitting a funding transaction to the blockchain network, wherein the funding transaction i) comprises a tokenised contract relating to an asset to be transferred from a second user to a first user; and ii) is signed by the first user.

The moderating effect of managerial discretion on blockchain technology and the firms’ innovation quality: Evidence from Chinese manufacturing firms

TL;DR: Wang et al. as discussed by the authors analyzed the impact of blockchain technology on innovation quality and found that managers with higher managerial discretion are more likely to leverage blockchain technology to facilitate innovation. And they also divided managerial discretion into environmental discretion, organizational discretion, and additional discretion in the Chinese context, analyzing their moderating effects on the relationship between blockchain technology and innovation quality respectively.

The Byzantine Generals Problem

TL;DR: The Albanian Generals Problem as mentioned in this paper is a generalization of Dijkstra's dining philosophers problem, where two generals have to come to a common agreement on whether to attack or retreat, but can communicate only by sending messengers who might never arrive.

The Byzantine generals problem

TL;DR: In this article, a group of generals of the Byzantine army camped with their troops around an enemy city are shown to agree upon a common battle plan using only oral messages, if and only if more than two-thirds of the generals are loyal; so a single traitor can confound two loyal generals.

In search of an understandable consensus algorithm

TL;DR: Raft is a consensus algorithm for managing a replicated log that separates the key elements of consensus, such as leader election, log replication, and safety, and it enforces a stronger degree of coherency to reduce the number of states that must be considered.
